HELP PLEASE MT5 Calendar tab is empty

 
HI Folks,

wanted to see if anyone here can help me. Here is my scenario:
when I open my MT5 the calendar tab is completely empty. I have installed MT5 from my broker "Darwinex" and also the generic one from Metaquotes website, both instance's calendar tab is completely empty and never populates. My PC is connected to the internet and connects just fine to my broker

When i install MT5 (same install file) on another PC it populates the calendar tab just fine. Can anyone hlep?
